About us
What we do
Northern Leaf operates a large-scale hybrid indoor and greenhouse medical cannabis facility in Jersey, the largest of the Channel Islands.
The company cultivates and processes high-THC cannabis flower for medical use and supplies regulated markets in the UK and Europe.
How we operate
Accredited to the highest standards, Northern Leaf holds a commercial licence from the UK Home Office that allows the cultivation, possession and supply of medical cannabis flower.
Strict pharmaceutical quality systems are in place across every step of the manufacturing process to ensure compliance with GACP and EU-GMP standards, which regulate how medicinal cannabis is cultivated, processed, tested and prepared for use in medicines.

How we grow
Northern Leaf’s cultivation and processing facility is based in St Lawrence, Jersey.
The site operates from a repurposed greenhouse originally built for horticulture and redeveloped for controlled-environment medical cannabis production.
The hybrid greenhouse uses advanced systems for CO₂ injection, automated irrigation, environmental monitoring and air purification to help reduce pathogen risk and support consistent growing conditions.
The growing area is divided into 20-by-80-meter compartments so different genetics and crop stages can run at the same time.
Drying and post-harvest processing take place in purpose-built facilities designed to control moisture loss and maintain product consistency.
